MS Access should not show hourglass automatically

[StefanSch]

Hello

I have a form in which users should add numbers. After every entry into the text boxes, MS Access performs some calculations on query level. As the calculation may last some 1 or two seconds, MS Access shows the hourglass automatically after every entry. How can I achieve that MS Access does not show the hourglass for this specific situation? (DoCmd.Hourglass False does not work since MS Access shows the hourglass automatically).

Thanks.

Stefan
